At a Musicians@Google event on Tuesday, Gaga stuck up for the 13-year-old singer -- who has been widely mocked on the Internet for her song, “Friday.”

“I think it’s fantastic,” Gaga said of Black’s fame through YouTube, where she has more than 35 million streams.

“I say Rebecca Black is a genius and anyone that’s telling her she’s cheesy is full of shit,” Gaga went on, although she noted that she hasn’t seen the video. Over the weekend, Simon Cowell defended Black as well.

Black says she has been cyber bullied for her song, which she recorded after her mom paid $2,000 to L.A.-based Ark Studios.

According to Billboard.biz estimates, she’s making about $27,000 a week from iTunes sales and YouTube streams.

During her long visit at Google’s headquarters in Mountain View, California, dubbed “Google Goes Gaga,” the singer plugged Google Moderator, a tool her fans use to submit text or video questions.

“At Google, we’ve seen Gaga build her career by embracing technology, as well as constantly innovating for her fans,” said the company’s Marissa Mayer.
